属性多级和项目多级评分的认知诊断模型

摘要

认知诊断理论中属性多级和项目多级评分均能极大地丰富项目信息,提高诊断结果准确度.基于此对已有认知诊断模型扩展的属性多级和项目评分多级的认知诊断模型进行介绍,并基于认知诊断模型和相关理论研究视角,对当前认知诊断的发展方向提出思考和建议.%Polytomous attributes and polytomous item in cognitive diagnosis theory can greatly enrich the item infor-mation and improve the diagnosis accuracy.Firstly,polytomous attributes and polytomous models are introduced which are extended based on cognitive diagnosis model.At last,based on the new models,some future research di-rections and suggestions are put forward to cognitive diagnostic.
